Daryn Sharp updated HDFS-1751: ------------------------------ Attachment: HDFS-1751.patch Add min/max component length, max items per directory. Full set of unit tests. > Intrinsic limits for HDFS files, directories > -------------------------------------------- > > Key: HDFS-1751 > URL: https://issues.apache.org/jira/browse/HDFS-1751 > Project: Hadoop HDFS > Issue Type: New Feature > Components: data-node > Affects Versions: 0.22.0 > Reporter: Daryn Sharp > Assignee: Daryn Sharp > Fix For: 0.23.0 > > Attachments: HDFS-1751.patch > > > Enforce a configurable limit on: > the length of a path component > the number of names in a directory > The intention is to prevent a too-long name or a too-full directory. This is > not about RPC buffers, the length of command lines, etc. There may be good > reasons for those kinds of limits, but that is not the intended scope of this > feature. Consequently, a reasonable implementation might be to extend the > existing quota checker so that it faults the creation of a name that violates > the limits. This strategy of faulting new creation evades the problem of > existing names or directories that violate the limits. -- This message is automatically generated by JIRA.
